Question

当我在Python命令中执行时

rssa = importr('Rssa')

我得到了eroor

Traceback (most recent call last):
  File "<pyshell#3>", line 1, in <module>
    rssa = importr('Rssa')

ValueError: Error: '...' already in the translation table. This means that the signature of the R function contains the parameters '...' and/or '...' <sigh> in multiple copies.

导入其他包时没有问题，例如

stats = importr('stats')
tseries = importr('tseries')
forecast = importr('forecast')

我一直在寻找这样的问题，但我找不到任何接近的东西。请提出一些关于这个问题的决定。

这是由于Rssa试图控制'分解'功能（从'stats'包中导出）时的错误引起的。特别是，在形式列表中'''被添加两次，这就是rpy2抱怨的内容。

这将在随后的Rssa版本中修复。

唯一的解决方法是在R / common.R中注释掉以下行：

formals(decompose.default) <- c(formals(decompose.default), alist(... = ))

从源代码重新安装Rssa。这在Windows上可能并不重要，尽管R windows构建器可以在这里提供帮助。

使用rpy2 importr将R包Rssa导入到python中
